What system should I use on my rephased motor?
Mikes XS now has in stock Pamco ignitions for both 277° and 270° rephased motors as well as stock ignitions at prices anyone can afford.
Here are some others we have tried along the way.
Ignition Install Guide
paper describes the installation and
issues I had when installing a Newtronic
(Yam6) pointless ignition kit into my
XS-650 1978 special. I took a few photos’
that will demonstrate some of the points
I will discuss. Hopefully this will be
of some use to our members in the XS-650
club thinking of fitting such a
I would recommend fitting a pointless
ignition system to your bike, once they
are fitted the bike will start and run
much smoother than with the older points
and condenser system. Secondly you never
have to worry about setting the timing
again, also with less moving parts this
has to be a better system.
fitting this unit was a bit of a task,
it proved to be worth while doing. If
anyone needs more information please

Wiring changed to make the bike run from supplied wiring diagram
which was wrong.

Electronik Sachse in Germany now make an ignition system for the standard XS650 but I emailed them and they are willing to make one for the 90° rephased motor. Click on the picture to check out their website. The price is estimated to be around AU$500.
Ignition System From Mark Whitebook at PROBE Engineering
There are now four distinct models available from PROBE engineering and information on them can be viewed on their new website at http://probe-engineering-inc.myshopify.com/
1/ DX-65G is a dual fire
ignition for a stock 360° motor (wasted
spark/single twin output coil) which is
factory set to 7500 rpm.
Dave Rayner's radical belt driven OHC posed a problem because he wanted to use the Boyer system as he could not keep the mechanical advance/retard mechanism, nor could he put one on each end of the cam for the rephased motor as an alternative. So he came up with the stacked Boyer ignition system pictured below. An expensive but workable solution and quite ingenious don't you think? Looks similar to the ARD magneto that was once available for the XS650 and nicely balances the belt driven OHC on the other side.
There is a new ignition system that has come onto the scene fairly recently called the Pamco which is by far the cheapest ignition system of them all. They are available through Mikes XS in several configurations, Standard timing, 277° rephase and also 270° rephase. Care should be taken as I'm told they are susceptible to failure if they become disconnected from the spark plugs whilst running. Apart from that they work great.
